    CPython extensions providing optimized execution of Python bytecode (like Cinder JIT and Pyjion)
    can benefit from being able to modify the vectorcall field on instances of PyFunctionObject to allow calling the optimized path (e.g. JIT-compiled) directly.

    We propose adding an API to allow extensions to override this field:

    void PyFunction_SetVectorcall(PyFunctionObject *func, vectorcallfunc vectorcall);

    this is now targeting 3.12 - how can I update the labels?

    GH-92257 adds this API and should be ready for review!

    Moved the labels for you, and started the tests running on the PR. Others will have to review it.
